Are there incompatible callings of the Disciples?

Question:

The book of John describes Jesus meeting Simon after his brother Andrew found him and told him about Jesus. Jesus then calls him Peter. Matthew, Mark and Luke describe Jesus seeing Andrew and Simon fishing and calls them to follow Him. Does this mean that Andrew and Simon did not follow Jesus after the encounter described in John and went back to fishing until Jesus called them later in the encounter described in the other Gospels or is there another answer?

Answer:

No need to reinvent the wheel on this one. I came across an excellent answer on Apologetics Press' website. The key assertion is that the synoptic (Matthew, Mark, Luke) gospels and John's gospel describe different events with calls with a different purpose.
